For high knee jumping lunges, you first push off the floor dynamically with your feet to jump straight up into the air. The upper body does not tilt backwards or forwards. Make sure that you catapult yourself straight up into the air. The front leg is naturally extended while you pull the back knee up towards your stomach. After the jump, you land in an upright position with both legs hip-width apart. Your upper body is upright and your lower back remains in a natural hollow back. You then jump into a lunge again. This time, however, the legs are positioned the other way round so that the back leg becomes the front standing leg and the former standing leg is extended backwards.
